| Research Abstract |
This study is mainly focus on the application of communication based on "sequency" to visible light communication systems. Visible light communication systems use LED as a communication devise by a fast modulation.
Wireless optical communication system that uses an LED traffic light as a transmitter and a high-speed camera as a receiver has been proposed. I have proposed a hierarchical coding scheme with 2D orthogonal transformation, such as Fourier Transform, Walsh Transform, Wavelet Transform. The coding method and the performance evaluated and confirmed the superiority of the system. Further, I have implemented the experimental systems and evaluated the performances. As results, I confirmed the effectiveness of the proposed system.
